_____ let you show only certain records on a table when you sort them.
zaharov [31]
I would say the answer is filters. They are responsible for showing entries that contain certain values according to the category you choose. For instance, you sort out the data by the date, when you choose from the filter list a certain date like jan 1, the sheet will be changed and will only show data for jan 1.

Which of the following describes how polluted water sources would most likely affect one’s personal health?
Bogdan [553]
I think the correct answer from the choices listed above is the last option. Polluted water sources would most likely affect one’s personal health since p<span>athogens would invade the body and cause disease, such as giardia. Pathogens would go with the water we take in our body and would disturb the processes inside causing illnesses.</span>

Replication origins have ________ DNA sequences that attract _______ proteins. A. A-T rich; histone B. G-C rich; Helicase C. A-T
goldfiish [28.3K]

Answer:

C. A-T rich; initiator

Explanation:

Replication origins have A-T rich DNA sequences that attract initiator proteins.

Replication origin is the DNA sequence where replication is initiated in a genome. The replication origin sequences is rich in adenine (A) and thymine (T) bases because it is easier to break the bonds between the bases compared to the bonds between guanine and cytosine. adenine (A) and thymine (T) bases have two bonds joining them as against three bonds between guanine and cytosine

The initiator proteins recognizes  DNA sequences in the replication origin and helps to initiate DNA replication.

What tissue makes up most of the wood of a tree? A. primary xylem B. secondary xylem C. secondary phloem D. vascular cambium
Over [174]

<u>B. Secondary xylem</u> tissue makes up most of the wood of a tree.

<h3><u>What exactly is secondary xylem?</u></h3>

Secondary xylem is a sort of xylem produced by secondary growth. During initial growth, in contrast, the primary xylem develops. As a result, the secondary xylem is linked to the primary xylem by lateral growth as opposed to the vertical extension.

The kind of cambium that gives rise to each difference is another point of differentiation. The vascular cambium produces the secondary xylem, while the procambium produces the primary xylem.

Unlike trees and shrubs, non-woody plants lack secondary xylem. It gives such plants mechanical support by depositing lignin into their cell walls, thickening them. Compared to the major xylem, the secondary xylem is made up of tracheids and veins that are shorter and wider. In comparison to the primary xylem, it is also richer in xylem fibers.

Possible growth rings in the secondary xylem (or annual rings). Sapwood and heartwood are two differentiators of the secondary xylem in big woody plants.
